WATER-FILTER.

Specification of Letters Patent.

Patented Dec. 23, 1913.

Application filed April 18, 1913. Serial No. 762,020.

To @ZZ whom t may concern Be it known that I, Sinorninn I'Inno, asubject of the Emperor of Austria-Ilungary, residing at Chicago, in thecounty of Cook and State of Illinois, have invented certain new anduseful Improvements in vl/rater- Filters, of which the following is aspecification.

rlhis invention relates to improvements in a water filtering,- device,and is intended for domestic or household use where the filtered watermay be drawn directly from the filter, or, in cases where it is desiredto filter the water and have the same stored in a receiving tank orvessel, from which the filtered water can be drawn, and it consists incertain peculiarities of the construction, novel arrangement andoperation oit the various parts thereof, as will be hereinafter morefully set forth and specifically claimed.

The principal object ot the invention is to provide a water filter whichshall bc simple and inexpensive in construction, strong, durable andefficient in operation, and so made that the filtering` material can beeasily removed from the casing or recep tacle therefor and withoutdisconnecting` the faucet through which the filtered water is drawn, orwithout disconnecting the conduit for the filtered water which leadsfrom the filter to the receiving tank or casing.

Other objects and advantages will appear in the following descriptionand explanation.

In the accompanying drawing, which serves to illustrate an embodiment ofthe invention,-Figure l is a central vertical sectional view of' a waterfilter embodyiiipr the invention; Fig'. 2 is a plan sectional view takenon line @-2 of Fig'. l, and Fig. 3 :is a view in side elevation of.' theupper portion of the filter, showing it equipped with a faucet andadapted for domestic or household use.

, Like numerals of reference rei'er to corre spending parts throughoutthe different views of the drawings.

The casing or receptacle for the filteringr material is designated bythe reference numeral 5, and may be of any suitable size, form andmaterial, but preferably of metal and cylindrical in shape as shown.This casing or receptacle has communication at its lower portion, andpreferably in its bottom, through a pipe 6, with a supply of water, andhas its upper end open. Near its upper end the casing` 5, is providedwith an inwardly extended annular flange 7, and above the saine in itsvertical wall with an outlet nozzle or projection 8, to which a pipe orportion of a faucet 9, may be connected by means of a coupling l0 oitthe ordinary or any well-known construction. The casing 5, is alsoprovided near its upper end and at dian'ietrically disposed points withbosses l1, each ot which is provided with a scrcw-threaded socket toreceive a screw bolt 1Q, which are used for pivotally connecting theends of a yoke 13, to said bosses. This yoke is provided at its middlewith a screw-threaded opening llt, Ylor the reception and operation ofan adjustillg screw l5, which may have on its upper end a winged knob orhandle 16, or other design, to be used for adjustinzg the saine. Theupper end ot the casing,I 5, is closed by a head cap 1.7, whichis-provided centrally on its upper portion with a boss or projection 1S,which has a socket 19, in its free end to receive the lower or free endotl the screw l5, which is employed in conjunction with the yoke 13 tohold the head cap l? securely in position on the open or .free end otthe casing'.

As is clearly shown in Figs. l and 2 of the drawings7 the cap 1T isprovided at :its upper part with a peripheral downturned llange 20,which, when the head is in posi tion on the casing', overlies oroverhangrs the upper end ot the latter. rlhe head cap 17 is alsoprovided with an annular or periph eral Lgroove Q1, which hascommunication through the tubular projection 8, with the pipe orit'aucet 5), and also has connnunication through a series o t channels2Q, with a central opening' 23, extended 'troni the bottom otl the headcap 17, upwardly therein. Located in the upper portion of the groove 2l,is a packing' ring;` 2li, ot any suitable nlaterial, which will rest atits outer portion on the upper end of. the casing 5, and thushermetically seal the same.

interposed between the flange 7, ot the casing 5, and the bottoni ol thehead cap l I. is a packing rino; Q5, ot any suitable niaterial, whichwill prevent the passage of water between the bottoni ol said cap andthe flange 7 ol" the casing. Located within the casing' 5, is a block 26of any suitable porous filtering;- niaterial such as l'rpolized stone,which may be ot a shape to conform @sul to the shape of the interior ofthe casing 5, and said block is provided with a central opening 27,which extends from end to end thereof, as shown. This block is connecterto the head cap 17, by means of a rod 2S, which is in screw-threadedengagement at its upper end with the cap 17, and has on its lower end adisk or plate 29, somewhat larger than the opening 27 in the block 26,of filtering material. interposed between the disk or plate 29, and thelower end of the block 26, is a washer or packing ring 30, which willassist the disk 29 in closing the lower end of the opening 27, againstthe admission of water therein.

The operation of the device is as follows: The water to be filtered issupplied to the casing 5, through the supply pipe G, from which it willenter said casing under pressure, and will rise therein and surround theblock 25 of filtering material, which it will be observed is spaced fromthe walls of the casing 5, so as to permit water to surround it entirelyfrom the flange 7 of the casing downwarc ly. As the block 26 is ofporous material the water will percolate through the saine and enter theopening 27, from which it will pass through the channels 22 into thegroove 21, of the head cap, and from thence through the outlet opening8, to the pipe 9, which, as before stated, may lead to a receiving tankor reservoir for filtered water, or, if desired, a faucet 9FL may beconnected to the outlet opening' S for the purpose of drawing thefiltered water directly from the filter.

By means of the yoke 13, and adjusting screw 15, it is apparent that thehead cap 17, may be firmly secured in place on the open or free end ofthe casing, and as said head cap rests on the packing rings 2st and 25,it is obvious that unfiltered water cannot pass into the groove 2l, andalso that leakage at the upper end of the casing will be prevented.

'Vhen it is desired to remove the filtering block 26, for the purpose ofcleaning the same, the screw 15 can be disengaged from its socket in theboss or projection 1S, when it is apparent the yoke 13 may be turneddownwardly and to one side of the casing, thus permitting the head capand block 26 to be removed without interference with the discharge pipesfor the filtered water or the faucet for drawing the same.

Having thus fully described my invention, what l claim as new and desireto secure by Letters Patent, is-

1. ln a water filter, the combination with a casing having an inlet andan outlet for water and one of its ends open and below said opening aninwardly projected annular flange, said outlet located between saidflange and the open end of the casing, a single piece cap to Aclose saidopen end of the casing and to rest on said flange and provided with acentral cavity in its lower portion and a peripheral groove incommunication with said cavity and outlet, said cap also having at thetop of its groove a depending peripheral flange, packing interposedbetween the upper surface of said groove and the open end of the casingand between the lower surface of the cap and the annular flange of thecasing, a hollow filtering block located on the lower surface of the capwith its cavity in communication with the cavity of the cap, a rodextended longitudinally through the filtering block and detachablyengaging at one of its ends the said cap, a plate detachably secured onthe opposite end of said rod and resting against the free end, of thefiltering block and closing the lower end of the cavity therein.
